THE ORANG-OUTAN (Simla satynts).
(Figs. 14 and 15.)
Configuration.—The Orang differs markedly from the Gibbons, for it is heavy in build, ugly in appearance and sluggish in its habits. The largest males are a little more than 4 ft. in height from the crown to the heels, but its great bulk makes it appear much longer. The females are a few inches smaller. The girth of the body may be nearly two-thirds of its height in inches, and the massive head frequently exceeds a foot in width. The
arms are very long, and their span, when they are extended at right angles to the trunk, exceeds the length of the body as in the Gibbons. Alfred Russel Wallace (293) states: "Five of this species, measured by me, varied only from 4 ft. 1 in. to 4 ft. 2 in. in height, from the heel to the crown of the head, the girth of the body from 3 ft. to 3 ft. 7^ in., and the extent of the outstretched arms from 7 ft. 2 in. to 7 ft. 6 in.; the width of the face from 10 to 131 in." Kollet, Blythe (231), Fick (247) and Brooke (234) give detailed measurements of a number of animals, and Huxley (87) records measurements made by Temminck, Schlegel, Muller, Humphrey and Spenser St. John. The abdomen is prominent, and the anus is more prominent than in Man.
The characters of the skull are continually changing throughout life, so that the facial appearances do not remain constant from maturity onwards. This fact was not known to many of the older writers, so that the data on which they based their specific distinctions are valueless. The brow is usually high and rounded, and may be hairy. The eyes are relatively close together, but
